The Profile Design 52ASC extensions bring the same CFD-refined carbon construction as the 43ASC but with a steeper 52° grip angle — better suited to riders who prefer a more upright wrist position or are transitioning from traditional round-section alloy extensions.

• CFD-optimised carbon fibre construction minimises aerodynamic drag without sacrificing structural integrity
• 52° sweep angle with 107mm rise suits riders preferring a more upright wrist and forearm position
• Aero-shaped carbon body sweeps outward to closely follow the rider's arm, reducing turbulence
• 400mm length provides ample reach for most rider builds
• 22.2mm clamp diameter with 16mm total offset for precise positioning
• Designed to pair with Profile Design Plus Series armrests

Carbon fibre gives the 52ASC a cross-section that an alloy tube cannot replicate — one that is narrower in the direction of travel and shaped to guide airflow cleanly away from the rider's forearm. The steeper 52° angle is particularly popular with riders who find the flatter 43° position puts unwanted stress on their shoulders during long-course triathlon efforts.

Compatible with any aerobar bracket using a 22.2mm extension clamp. Minimum usable length from front of clamp is 290mm. Pairs best with Profile Design Plus Series armrests.
